Specification

Safety in the Laboratory
• Transparent Protective Door
Offers protection against splashes and facilitates observation of the distillation process.

• Safety Functions
Distillations can only be started when the tube is inserted properly and the protection door is closed.

• Monitoring Functions
Should there be any malfunction, the analysis is stopped or aborted immediately.

• Automatic Steam Generator
Pressure control and overheating protection of the steam generator offer absolute protection.
Resources in the Laboratory

• Saving energy - Stand-by mode
The instrument switches automatically to the stand-by mode during non-operation periods. During the standby mode the steam power is maintained. This feature ensures full steam power for distillations even after long breaks.

• Saving Cooling Water
When the equipment is in the stand-by mode the cooling water supply is cut off automatically.
Quality in the Laboratory

• Direct Addition of Water Steam
Optimal blending of the sample, so that crystallized digestion solutions are liquefied in seconds.

• High Quality Material
All material used have been tested intensively in Gerhardt’ s own application lab.

• Plastic Housing
Corrosion caused by chemicals is practically impossible. Thus, the life span of the instrument is dramatically increased.
Highly Precise Analysis in the Laboratory
With the introduction of the Vapodest distillation systems C. Gerhardt has set new standards in today’ s worldwide analytical
instrument market. Whenever, highly precise analysis results are needed - C. Gerhardt has the answer. Vapodest offers solutions for demanding tasks in tomorrow’ s lab. All systems have an automatic steam generator with a steam output, which can be set between 40 - 100 % ; thus all common distillations can be handled easily. Since the instrument is kept in stand-by mode when it is not needed, energy is saved but an immediate start of an analysis is also possible at any time. A wide range of distillation times can be programmed. Typically Kjeldahl-distillations are finished in 2-4 minutes. The Vapodest models with improved distillation time range from a semi-automatic distillation system, the Vapodest 10s, to a fully automated distillation and titration system, the Vapodest 50s carousel with autosampler and controll via PC.

Operation via Operator Button
The instrument is operated very easily using an operator button. All steps of the analysis and the programming as well as error messages are shown in the display clearly visible. Suction and addition of chemicals can be programmed or done manually using the chemical resistant key board.

Operation via PC - Vapodest Manager
Model Vapodest 50s and Vapodest 50s carousel are operated via PC using the controlling software Vapodest Manager. This software offers extensive documentation- as well as monitoring functions and meets the requirements for certified laboratory management

Applications
Vapodest observes international and national norms and analysis standards and thus, meets the requested analysis qualities. Vapodest can be used for nearly all analytical areas. Application notes for various determinations are available on request.
